This invention/'relates to new and useful.

improvements in separating batlles for oil and gas separators.

Gne object of the invention is to provide bailies .for insertion in the fluid opening'sof a separator shell, whereby the liquids'flow-l v ing down the inner and outer surfaces ofthe shell ,are deiiected from. the openings and also whereby the fluids-are compelled tosurmount the `lsaiiies before gainin access to the passages therethrough and t us causing a further separation of the liquids.

motion and its velocity `is increased.

A construction designed to carry out the d invention willbe hereinafter' described, toe

Fi 2 is a sectional detail showing thebagether with other features of the invention.

The invention will be more readily understood from a reading of the following specification and by reference to the accom any ing drawin s, in which an example of t e in.- vention is s own and wherein :A

Fig. 1 is a vertical sectional view Aof a typical oil and gas separator equip ed with baies constrpeted in accordance w1t the ines 1n place, together with the scrubbing Fig.' 3 is equipped with vanes, and

Fig. 4 is a sectional detail showing one o f the b'aiies illustrated in Fig. 3.` In the-drawings the numeral l() designates an ordinary separator tank having an indu-J,

ent inlet 11 at'mid-height and an" oil outlet 12 near its bottom, to ether with a gas discharge pipe 13. Wit in the upper portion e pasa detail showing the 'baises' of. the tank is mounted an outer scrubbing shell 14 and an inner scrubbing shell 15 spaced therefrom. The outer shell has' inlets near its to The ausili which risa in the tank from the' c inlet 11,.,pass. upward and enter the shell 14 through the opening 16. Theseiuids which, to a large extent, are gas includealso a proportion of oil or liquid in the form of glob-v ules and as they pass downwardly ina helical course around the shell 15, they are scrubbed a ainst the outer surface of said shell with the result that the liquids tend to adhere and trickle down the outer surface of said As it is desirable to still further scrub the vfluids and extract as much li uid as possible,

openings 17 are provided in t e shell 15 near its bottom so that the gaseous fluids ma enF ter the shell for further treatment. t 1s not desirable, however, to have the liquids "which have been extracted. and are passing down the outer surface of the shell 15 car ried through said openings. I, therefore, in,

sert tubular baiiles 18 in said openings which are secured to the shell intermedlate their ends so as to project from both the in ner and outersurfaces 'of said shell. It

lwill be seen that the liquids will be caused to flow around the louter proJections of vsaid battles andalso tliat those fluids flowing conf tiguous to the outer surface of the shell must pass outward and over the edges of v,said Vbaffles in order to enter the same,

thereby going through anV additional scrubbirg.

wing to the reduced diameter'l of the baliie, the velocity of theflowing fluids will be increasedjand said vfluids will be directed against ,the outer wall of a concentric def flector 19 disposed within the shell,'whereby a further scrubbing and extraction of liquidsA will be carried out.y ALiquids flowin down. the' inner surface of the shell 15 wi l be deflected out of the path of the inflowing ,l n

iiuidsby the bailes 18.

In Figs. 3 and 4 I and cause them to `t e a have' shown a twisted vane 20 fastened in each baille 18 andsueh vanes will obstruct the assa e of; the duide elieal course.

This will cause an additional scrubbing and extraction of the liquids and will give to the fluids a whirlingmotion which will enhance the scrubbing action, both in the baie and against the wall of the delector 19.

Various changes in the size and shape of the different parts, as well as modifications and alterations, may be made within the scope of the appended claims.

What I claim, is: i 1. The combination in an oil and gas separator, of a tank, a vertical scrubbing shell within the tank closed at its upper end and having openings at its lower portion,

an imperforate vertical defiector disposed within said shell, tubular baiiies surrounding said openings and projecting from the outer and inner surfaces of the shell at an angle to the'tank wall with the inner end of said baifles spaced from the deflector suiiiciently to permit entrained gas to escape before striking the defiector, and a gas discharge communicating with the space surrounding said deflector.

2. The combination defined .by claim 1, with the tubular baiiies provided with twisted vanes disposed within the same.

In testimony whereof I affix my signature.
